							NOTE:By recycling the bolt backwards and forwards, loaded rounds
should enter into the chamber in a controlled manner. In other words, the
rim of the cartridge case should slide up into the bolt face as the bolt is
moved forward and cartridges picked up out of the magazine. The cartridge
will then feed into the chamber. The bullet should not touch any part of the
mechanism as it is feeding into the chamber.
E1. Unloading the Rifle
1. Point the rifle in a safe position.
2. Place the safety into the SAFE position (see photo A2).
3. Raise the bolt handle and slide the bolt slowly to the rear position with
your free hand over the ejection port.
4. Remove cartridge with free hand.
5. Once the first cartridge is removed, place your hand under the floor plate.
6. Push the Trap door release latch to drop the trap door plate (see picture
D3). The magazine spring, follower and cartridges will be released from
the magazine.

1. Repeat Steps 1 through 4 in section E1.
2. Keeping the muzzle pointed in a safe direction, push the bolt handle
slowly forward, just until the next cartridge is released from the magazine.

the bolt if the bolt is pulled rearward. If the cartridge remains in the
chamber, then you must slide the bolt all the way forward and push the
bolt handle downward to close the bolt. THE GUN IS NOW READY TO
FIRE. Then repeat #1-4 of section E1 to remove the cartridge. 
3. Pull the bolt handle slowly to the rear position. With your free hand over
the ejection port, the cartridge should come free of the bolt.
4. Repeat #2 & 3 until the magazine well is completely empty, and the
chamber is empty.

G. Removing Barreled Action from Stock
When taking the barreled action out of the stock, the following procedure
should be carefully followed to avoid damage to stock.
1. Place the safety in “Position 2” safe Mode (see Fig. A2).
2. Remove Bolt assembly (see Section C).
3. Remove both takedown Screws from trigger guard (see photo G1).
4. Carefully lift the barreled action from the stock taking particular care to
protect the wood around the receiver tang area. 
5. The Magazine Well can easily be removed from the action for cleaning
(see photo G2) by lifting the forward section up slightly then pull entire
Magazine Well out of the action. To re-install carefully slip the rear of the
Magazine Well into the action until bottomed out then push the front
down until seated snugly in the action.

Bolt disassembly NOTE:Further disassembly of
the bolt is not recommended. If
for any reason you cannot
assemble the bolt together, do

							H. Trigger
The trigger is a single stage mechanism which is set at the factory for
between 3 -1/2 and 4 lbs. for Varmint Models and between 3-1/2 and 4 lbs.
for the Classic Models. 
It is fully adjustable for over travel, depth of sear engagement and weight of
pull. However, the trigger pull has been set at the factory with proper
overtravel and sear engagement, so we do not recommend disassembly or
adjustment except by a qualified gunsmith or by our factory personnel.
Only experience Kimber gunsmiths should
adjust the trigger mechanism.

THEN LIFT UP AND OUT AT SLIGHT ANGLE 
FIRST LIFT UP SLIGHTLY
If for some reason the trigger guard must be removed from the stock, the
best way to achieve this is to lightly tap each end of it, fore and aft, with the
tip of a screwdriver from inside the stock.
To return the action to the stock, reverse procedures 1 through 4. Be sure to
tighten the front take down screw first, then the rear screw. 
						

							I. Action – Cleaning  & Care
When it is necessary to clean the action, the stock should be removed. Clean
the action with a good quality gun cleaning solvent such as Shooters Choice
Extreme Clean or other quality gun solvent. Follow Manufacturers
directions then re-oil lightly with Shooters Choice FP-10 or other high
quality gun oil. The cocking cam surfaces on the bolt should be kept
lubricated. 
NOTE:Use oil in moderation, remember more is not better. A light coating
is all that is needed.
J. Barrel  – Cleaning
Always visually check the chamber and magazine to assure no cartridges are
in the rifle. 
1.  Always use a good quality cleaning kit with the proper caliber rods and brushes.
2.  Follow gun solvent manufacturers cleaning instructions for bore cleaning.
NOTE: Some gun bore solvents are extremely aggressive to metal  & wood
finishes, Kimber accepts no responsibility for damaged finishes due to
misuse of solvents. 
3. Remove bolt assembly (see Section C).
4. Use correct cleaning rod and patch attachment. 
5. Run patch completely through bore from the action end, once the patch
is clear of the barrel, wet the patch with solvent. Pull the rod through the
barrel to wet the inside thoroughly (this will assure no solvents will leak
down into the action and into the wood stock. 
6. Change to correct caliber brass cleaning brush.
7. Push the brush completely through the bore exiting to the front of the
barrel. Place solvent on brush then pull the brush back through the barrel.
SPECIAL NOTE: Always make sure the ejection port is facing towards the
floor and the barrel is horizontal on a flat protected surface so as to allow
excess solvent to fall away from the workings of the gun.
8.  Push the cleaning rod and brush from the action end through the barrel
bore several times. 
9.  Remove brush and replace with swab/patch tip then push through bore.
10. Repeat steps 5 - 7several times until the fresh patches come out clean.
11. Push a dry patch through the bore to remove any solvent residue.
12. Wipe exterior surface with a lightly oiled cloth.
13. If storing for any period of time, lightly oil the inside of the barrel.
Remember to always remove any oil from inside the barrel before firing.

							K. Care and Cleaning
When storing any firearm, always thoroughly clean and oil. Outside surfaces
should be wiped with a light coat of oil or good quality rust preventative
such as Shooters Choice Rust Prevent or equivalent.
Before firing any firearm, be sure to remove all excess lubrication from the gun,
making sure the chamber and bore of the firearm is clean and dry of any oil.
Handling leaves invisible prints of moisture that can cause rust to metal
parts. Always wipe receiver and barrel with an oiled cloth after handling.
Rust is neglect.
Abrupt temperature changes cause condensation and moisture; therefore,
special care to interior metal parts is needed to prevent rusting.
Do not store the rifle overnight in the truck of a car, even if it is inside a soft
gun case. Humid, cool conditions can cause condensation and rust in a short
period of time.
Insure that a light coating of oil is maintained on the bolt and receiver thus
insuring a smooth fluid functioning of these two major parts.
Warning: after cleaning the bore, always check to see that no
part of the cleaning rod or part of a patch remains inside the
barrel as an obstruction.
The wood stock on your gun requires very little care. Wipe the wood stock
of your Kimber rifle with a good quality wood or furniture polish or wax.
Using this method will enhance the beauty and durability of your rifle.
Owners of Models with Kevlar Synthetic Stocks
Your synthetic stock should give you years of trouble free performance if
you follow a few simple rules. 
1. Do not
use Degreasers, Lacquer Thinners or aggressive Cleaners on your
stock! The finish will not be covered under Warranty if damage caused by
solvents or aggressive cleaners is evident. 
2. To avoid Bore solvents from dripping and settling into your stock, remove
the stock from the action when cleaning the rifle. (see section G,#1-4
Removing Barreled Action from Stock) If solvent comes in contact with
the stock, immediately wipe the solvents from the stocks finish. 
3. For cleaning, use only soap and water or mild Car Washing Detergent.
Allow to air dry before reassembling the rifle. Never
use solvents to clean
your Stock.

							L. Dry Firing
Going through the actions of cocking, aiming and pulling the trigger of an
unloaded gun is known as dry firing. Dry firing can be useful to learn the
feel of your new Kimber rifle. Be certain the rifle is unloaded and pointed in
a safe direction even when practicing. Your new Kimber rifle can be dry
fired withoutdamage to the firing pin or other components.
M. Maintenance
This rifle should be checked periodically by competent gunsmiths to ensure
proper function and replacement of any worn or damaged part. This is best
performed at the factory by Kimber trained gunsmiths.
N. Lead Warning
Discharging firearms in poorly ventilated areas, cleaning firearms, or
handling ammunition may result in exposure to lead and other chemicals
known to cause birth defects, reproductive harm, cancer, and other serious
physical injury. Have adequate ventilation at all times. Wash hands
thoroughly after exposure.
O. Scope Mounts and Bases
The Model 8400 Rifle Receiver is drilled and tapped for Kimber two piece
contoured scope mount bases. The front scope mount base is different from
the rear. Order only Kimber rifle scope mount base in sets. They are
available from your dealer or from our customer service department in
Yonkers, NY. Remember that you will need one base for the front and one
for the rear. The screws and wrench are supplied with the bases.
The Kimber scope mount bases will accept Redfield, Leupold and Burris
rotating front dovetails and windage adjustable rear ring sets.
Before ordering scope rings is very important to first decide on the scope
you want to fit. This will have a bearing on the height of the rings you need
to order.
Most styles of rings come in at least three different heights. Medium height
rings should be adequate for all standard size scopes. Low and high rings are
available for special applications.
